I can take care of all the above trades.

I am fair but very firm with them.I generally use the same subs at each job (with an alternate for each trade to keep their prices competitive), occasionally I jettison an under performing sub off to the abyss which sends a clear message to the other subs that I'm not afraid to make changes mid-stream if needed.I buy all materials, subs do not (except rough items by plumber and electrician).

Just a thought.Thinking a little bigger, you can also get into trades, equity sharing, investors might do 1031 exchanges.

There is no particular correlation between math and finance.There absolutely is a reason for this.Mathematicians develop computer algorithms/mathematical formulas that are used in high frequency trading (HFT).http://en.wikipedia.org/wiki/High-frequency_trading

It will also give you perspective so that you can keep an eye out for cheaper or more effective trades/materials.

I would suggest analyzing the comparables and copying which designs you feel are effective to get a sale.Then you can get the labor cost from a contractor or trade.

Credit reports simply provide a history of an applicants past trade lines and fairly often, rent is not one of them.Additionally, credit reports do not reflect alternative lending, and knowing that the majority of renters are sub prime or borderline sub prime, this means that your renters will likely have monthly debt obligations that you are completely unaware of when calculating their debt to income ratio.

The deed was mailed to my office and I traded them the deed for the difference ($18,000 profit).

there might be plenty of other hazards on the job site that me as a building owner is responsible for …hanging wiring, maybe a beam that is just waiting to fall on somebodyAlso ..we all know we should hire licensed guys …but there are a lot of unlicensed trades who are skilled in what they do and price competitive …if I hire an unlicensed person as a contractor and he does damage to the building or his work caused somebody to get hurt…would my general liability insurance be the one to take from there ?
